With additional linear axis and groove wall offset (transformation type 514):
On a machine with a second linear axis, this transformation variant makes use of
redundancy in order to perform improved tool compensation. The following conditions then
apply to the second linear axis:
• a smaller working area and
• the second linear axis should not be used for the travel through the parts program.
Certain machine data settings are assumed for the parts program and the assignment of the
corresponding axes in the BCS or MCS, see

Offset contour normal OFFN (transformation type 513)
To mill grooves with TRACYL, the following is programmed:
• groove center line in the part program,
• half the groove width programmed using OFFN.
To avoid damage to the groove side OFFN acts only when the tool radius compensation is
active. Furthermore, OFFN should also be >= the tool radius to avoid damage occurring to
the opposite side of the groove.
